I have just done an install of Lubuntu 20, and was following the instructions from the launchpad PPA site:
https://launchpad.net/~hugin/+archive/ubuntu/hugin-builds I did this: sudo add-apt-repository ppa:hugin/hugin-builds but got the error/warning message: Reading package lists... Done E: The repository 'http://ppa.launchpad.net/hugin/hugin-builds/ubuntu focal Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default. N: See apt-secure(8) manpage for repository creation and user configuration details. Can anyone advise how I persuade my system to use this PPA?
